Description
In the Linux kernel, the following vulnerability has been resolved:
ethtool: tsinfo: don't pass ERR_PTR to genlmsg_cancel on prepare failure
The goto err label leads to:
genlmsg_cancel(skb, ehdr);
return ret;
If ethnl_tsinfo_prepare_dump() failed, it has not started a genlmsg.
There's nothing to cancel, and passing an error pointer to
genlmsg_cancel() would cause a crash.
Affected configurations
• linux linux kernel (>= 6.14 < 6.18.35)
• linux linux kernel (>= 6.19 < 7.0.12)
• linux linux kernel 7.1
